Arduino Powered Brain Machine 

It is basically an Arduino and LEDs that have been mounted on a pair of safety glasses. It 
runs a code that you can modify so that you get a strobe that is in front of your eyes. When 
you put them on, they help you see crazy patterns and things, and when you take them off, 
you feel wonderful (except for people that are sensitive to strobe lights). 



Step 1 — Solder up the LEDs 




• Put on the glasses. Mark where the center of your eye is on the glasses. Drill out the 
marks with a 3/16" drill bit. Cut out the graphics so that they fit on the glasses. Burn a hole 
in the center of the graphics. Push in the LEDs through the holes you just made. Solder 
two 5" wires to the LEDs. Solder the black to black and red to red. Solder two 1" wires in 
between the connections you just made. Hot-glue everything in place. Hot-glue the 9V 
battery on the right arm of the glasses.

Step 2 — Mount and Program the Arduino 




• Use a tiny dab of hot glue to glue the Arduino to the left arm of the glasses. Use a zip tie to 
make it tight. Plug the black/negative wire from the LEDs into ground. Plug the red/positive 
wire from the LEDs to pin 13. Plug the Arduino into your computer using the USB cable. 
Open the IDE. Load the Blink example sketch by going into File> 
Examples>1.Basics>Blink. Change each of the 1000 millisecond delays to 50 
milliseconds. (aka change the "1000"s to "50"s) Click Upload. The LEDs should start 
flickering.

Step 3 — Use it 




• Plug the 9v battery on the right side to the Arduino on the left side using a connector. The 
connector is a wall adapter to Arduino plug adapter. Split a 9v battery connector in 
between the wires. (If you have an Arduino connector to 9v battery connector, than use 
that instead.) Plug the 9v connector end into the 9v battery. Plug the other end into the 
plug on the Arduino. Put on the glasses. Relax... Think about patterns... Use the 
headphones plugged into the phone or mp3. Set the volume on Med-Low volume. 

• Do not use for more than 3 minutes. This is not for people that are photosensitive to 
flashing lights.
